NAME

       jbig2dec - File format converter specialized in JBIG2 decoding

SYNOPSIS

       jbig2dec [options] file.jbig2
       jbig2dec [options] global-stream page-stream

DESCRIPTION

       The jbig2dec command converts JBIG2 files to png or pbm files.

       When passed a single file argument it is interpreted as a JBIG2 file stream, with either sequential or random-access organization.

       When passed two stream arguments, they are interpreted as the global and page-specific portions of an embedded organzation, as used in PDF.
       If a particular page references no global segment stream, /dev/null can be passed for the global-stream argument to  request  the  embedded
       parser.

OPTIONS

       The options are as follows:

       -o file
	      Store the decoded output in file.  Defaults to the input with a different extension.  Set to - for standard output.

       -t type
	      Force a particular output file format. Supported are png and pbm.

       -d or --dump
	      Print the structure of the JBIG2 file rather than explicitly decoding it.

       --hash Print a hash of the decoded document.

       -q or --quiet
	      Suppress warnings and other diagnostic output.

       -v or --verbose
	      Report  additional information about the decoding process.  Pass just -v for information about the file as it's being decoded.  This
	      is the same as --verbose=2.  Pass --verbose=3 or higher for debugging information.

       --version
	      Show program version information.

       -h or --help
	      Show usage summary.
